|
The ashmem subsystem is a new shared memory allocator, similar to
|
|
POSIX SHM but with different behavior and sporting a simpler
|
|
file-based API.
|
|
|
|
It is, in theory, a good memory allocator for low-memory devices,
|
|
because it can discard shared memory units when under memory pressure.

This enables 'Android-Style oom-killer'
|

The way to select victim by oom-killer provided by

linux kernel is totally different from android policy.
|
|
Hence, it makes more sense that we select the oom victim
|

as android does when LMK is invoked.
